Biological Information Measurement Device Using Level Indicator for Arrhythmia Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biological information measurement devices struggle to enable users without medical knowledge to easily recognize arrhythmia, as they rely on blinking heart marks and time-series graphs that are difficult to interpret.
Innovation Solution
A biological information measurement device equipped with a pulse acquisition mechanism, a pulse interval calculation mechanism, and a display mechanism that uses a level indicator to visually represent the pulse interval or changes in it, allowing users to intuitively recognize arrhythmia.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a time-series graph of pulse wave signal level is displayed, then pulse interval information can be read, but it is difficult for users without medical knowledge to correctly interpret arrhythmia information
Solution Approach 1:
The patent transforms the pulse interval data from a continuous time-series graph into discrete level indicator segments that represent different pulse interval ranges. This parameter transformation converts complex temporal information into simplified categorical visual elements that are easier for lay users to interpret, directly addressing the contradiction between information preservation and ease of interpretation
Solution Approach 2:
The patent divides the pulse interval information into multiple level indicators, each representing a specific range or characteristic of pulse intervals. This segmentation breaks down the complex time-series data into discrete, easily distinguishable visual elements, enabling users without medical knowledge to quickly grasp arrhythmia patterns without needing to interpret continuous graphs
2Loss of information
If a blinking heart mark is displayed to indicate pulse interval, then the device can show pulsation information, but users cannot intuitively recognize fluctuations in pulse interval
Solution Approach 1:
The patent adds a spatial dimension to pulse interval representation by using level indicators with varying positions, lengths, or intensities rather than relying solely on temporal blinking patterns. This dimensional transformation allows users to intuitively perceive pulse interval fluctuations through spatial variations in the visual display, resolving the contradiction between information retention and intuitive recognition
3Loss of information
If detailed time-series pulse wave data is provided, then complete arrhythmia information is available, but users perceive it as objective unrealistic information without sense of urgency
Solution Approach 1:
The patent employs variations in visual properties of level indicators (such as intensity, color, or size) to encode the significance of different pulse interval patterns. This visual encoding transforms neutral data presentation into emotionally resonant feedback that conveys urgency and importance, enabling users to perceive arrhythmia risks with appropriate concern while maintaining complete information accuracy

AI summary
A biological information measurement device includes a pulse acquisition mechanism configured to detect a pulse of a human body, a pulse interval calculation mechanism configured to calculate, based on the pulse, a pulse interval between one beat and a beat immediately before the one beat, and a display mechanism configured to display a level indicator visually indicating at least one of the pulse interval or an amount of change from another pulse interval immediately before the pulse interval. The level indicator indicates, per beat of the pulse detected, the pulse interval or the amount of change.
